Researchers have developed new methods for backdoor attacks on advanced AI models, specifically targeting Vision-Language Models (VLMs) and Diffusion Models (DMs). One approach, CBV, uses diffusion models to create natural-looking poisoned examples for VLMs by subtly altering image generation processes and focusing modifications on semantically important regions. Another method, Gungnir, exploits stylistic features within images as stealthy triggers for diffusion models, making attacks harder to detect and bypass existing defenses. AI
